hi! love your drawing skills! i guess the best thing i ever came up with was starting to use the real dbh shirts from the shop a click away for my design templates. you just gotta do some cleanup in photoshop first to get rid of the original design. this really gives you a lot better idea of how your design would look in real life and helps you think of ways how to improve it! so good luck! sure hope to see more pieces from you of that quality!
